My mother deeply disappointed me tonight

My mother deeply disappointed me tonight I (17M) have been stuttering since I was 7 years old, even though I just noticed in my health record some time ago that from the age of 4 the doctors were already worried about my stuttering and that it could have been resolved much earlier if my parents had bothered to care, but that's not the point. This evening I had a discussion with my mother about my stuttering. According to her, it's because of my emotions that I stutter, and it's this stuttering that prevented me from growing much as a child (I'm 1m64 and I'm self-conscious about my height) because it stresses me out. She also gave me the causes of my stuttering, which would be: - my isolation (I talk a lot on a daily basis, I just avoid people at church when she takes me there by force). - my emotions, she thinks that I am stressed or angry on a daily basis or not at all (except this evening) - And of course... the screens! According to her, it would constantly excite my brain and that's what would drive me CRAZY. She actually said that word to my face. It showed me how she really perceived me. It shocked me deeply, I even cried. That wasn't the only thing she had done to me. Some time ago, she wanted to treat my stuttering with amateur hypnosis, which was basically a bad speech therapy session (bad advice, bad hypnosis, €40 for 30 minutes) And she told me that it pissed her off that I couldn't say hello correctly while belittling him, and kept giving me advice that makes you want to tear your head off like "slow down, breathe etc" which I already do and which cannot help me anymore. It annoys me to see my mother not supporting me and pushing me into my problem "to help me", the fact that she calls me "crazy" makes me feel like I'm not understood in my own family.
